APPARATUS FOR TREATING OIL Application filed September 1, 1920, Serial No. 407,405. Renewed October 15, 1926.

This invention relates to improvements in a process and apparatus for treating oil and refers more particularly to a process and apparatus adapted for the use in simultaneous 5 cracking and dehydration of 'emulsiiied petroleum oils at atmospheric pressure.

The object of the invention is to providea novel process and form of apparatus in which the oil may be dehydrated and distilled by surface distillation and in which the vapors may be superheated to a cracking temperature at atmospheric pressure While at the same time rotatin fective distillation and prevent local overheating of the apparatus itself.

In the drawings, Fig. 1 is a view partly iii side elevation and partly in vertical section of our improved apparatus. Fig 2 is a similar view of the still member proper on an enlarged scale.

Referring to the drawings, 1 designates the firebox provided with a stack, 2. In this iirebox is mounted a double still member consisting of a lower shell, .3, and an upper shell, 4. The shell member, 3, is provided at either end with a cireumferentially extendin gear, 5, supported on a trunnion, 6, carrie by a standard, 7 At one end the shell member, 3, is provided with a driving shaft, 8, and driving pulley, 9, connected to any suitable source of power (not shown). The upper stillshellmember, 4, is provided at either end with a circumferentially extendin gear,vl0, which meshes by means of interme iate gear, 11, with the corresponding gear member, 5. The arrangement is such that the shell members, 3 and 4, are rotated in the same direction. It is to be understood that the shell members are supported in suitable vguides (not shown) to prevent lateral displacement. Each shell member is open at one end to connect with a cap portion or`stationary shell member, 12, and the rotating parts of the still are connected tothe stationary parts through the ground joints, 13, or other suitable rotatable connections. The oil to be treated is charged by means of pump, 14, and line 15, to the stationary part, 12, of the lower shell member, 3. Eachof the stationary parts, 12,

is provided with a residue drawoff, 16, confr the stills to insure a more ef-A trolled by valve, 17. The vapors generated 1n the lower shell member, 3, pass to the upper shell member, 4, by means of the pipe co11- nection, 18, connected. to the stationary members, 12, and preferably provided with an extension, 19, projecting into the body of the upper rotating member, 4.

The vapors pass out of the upper stationary part, 12, through line, 20, to condenser coil, 2l, and thence to receiver, 22. If desired, the valve, 23, may be interposed in the line, 20. The oil is subjected to surface distillation in the shell. 3, by means o'f a pair of burners, 24, arranged at opposite sides of the upper part of the shell, 3, and extending longitudinally alongside of the latter as shown at 25. The inner faces of the'burner, 24, are slotted to distribute the heat equally over the entire length of the still lor shell, 3. These burners, 24, are arranged at or above the liquid levell in the shell, 3, so as to primarily heat the up shell member at a temperature sufficient to dehydrate the oil and gradually fractionally distill the vapors while at the same time maintaining the temperature sufficiently low to prevent undue heating of the emulsiiied oil which would cause foaming. By independently heating the upper still member, the vapors themselves can be superheated to such a temperature as to produce substantial cracking of the oil vapors thereof. For example, if

the process is carried out at atmospheric pressure the oil 'in the lower still member might be subjected to surface distillation ata temperature of from 450 F. to 750 F., while the vapors in the upper still member might be heated at a temperature of 800 F. to 1200".
